摘要
基于通用有限元分析系统ABAQUS的用户子程序二次开发实现Ducan-chang双曲线模型,对某混凝土面板堆石坝(CFRD)的填筑与蓄水过程三维非线性有限元仿真模拟,得到了坝体和混凝土面板的应力与变形、混凝土面板的垂直缝和周边缝沉陷、剪切和张开变形等结果,对工程坝体断面优化分区、接缝止水设计提供了参考依据。
The Dun-Chang constitutive model was implemented by using User Subroutine in ABAQUS which is a general-purpose finite element analysis system. Stresses and movements analysis for a concrete face rockfill dam （CFRD） during the phases of deposition and water impounding were simulated by 3-D nonlinear finite element （FEM）. The magnitude of opening,sliding and sinking about the vertical and circumjacent aperture on the face was obtained. All results are reasonable and capable of providing important reference to the optimization of cross section zones and design of sealing system for the project.
